DRIVING-GEAR FOR moron-vnrnonns.

' Specification of Letters Patent.

Application filed Maroh2l,190.7. Serial No- 363,981.

To ollwhom it may concern: I

Be it known that we,- CHARLES RICHARD BINNEY and James LOGAN 'WATKINS,both citizens of the United Kingdom of Great Britain and Ireland, andresidents of 5 Hackney road and 251 Clapha'm road,

- both in London, England, have invented' certain new gear for motorvehicles and refers more particularly and useful Improvements inDriving-Gear for Motor- Vehicles, of which the following is aspecification, suchas will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in driving I required. The cam ispreferably of disk or plate form,

and is driven by the engine and is arranged or constructed with one facehaving ia depression or its equivalent, preferably a trefoil depressionby which a lever is moved. I The cam end of this lever'is con nected toone end of an arm the other end of which ispivotally attached to a fixedpart of the frame or forecarriage. A roller is attached to the arm orlever and travels in the cam depression which as it rotates reciprocatesthe arm, thus obtaining the required movement of the eccentric the headof which is mounted on the shaft which it is required to drive. Theother face of the ohm (or a separate disk or plate on the same shaft) isprovided with a series or set of teeth which engage a worm gear on theend of a shaft the other end of which also carries worm gear and engagesand drives a toothed wheel on the same shaft as that driven by theeccentric. This worm gear shaft can be raised or the gear otherwisedisconnected so that the cam drive only can be used. The cams may bearranged in duplicate, in triplicate or otherwise and 'a general orconvenient method of mounting the partsis shown in the accompanyingdrawings in whicliz- Figure 1, is a detail view in elevation of the camand its intimate parts employed in this invention. Fig. 2, is a viewtaken on the reverse side to that shown in Fig. 1, certain parts thereofbeing omitted and others disclosed. Fig. 3, is a plan view of apair ofcams with eccentrics and one worm showing convenientrelative position ofthese parts and of the engine shaft reversing gear and the clutch anddifferential gearing. Fig. 4, is a plan view ofthe gear eccentric.

arranged in a circular forecarriage and ,shows two pairs of engines,each'driving a 'setof gear similar to that in Fig. 3. Fig. 5, is asectional 'view on line 5-5 of Fig. 4. I

depression I), the cam is mounted by sleeve con shaft d. An arm e ispivoted at one end to frame work f and at the other end to rod 9 ofeccentric h. This arm carries roller 1' which travels in the deprea tionb as the'latter rotates. The eccentric is mounted by sleeve j on shaftk, which it' drives through any convenient clutch and difierential orother gear. 0n

which also carries a second worm 0 adapted to drivethe toothed wheel pon the sleeve 'driven by the 1, 1 are the engines or motors,which may beof any convenient type and drive the shaft d.

The direction of drivemay be --horiaontal, as

shown, vertical or otherwise and the shapes and arrangements of theparts may vary in any suitable and convenient way. I

We are aware that cam driving gear has previously been employed formotor driving vehicles and we make'no'claim. for the exclusive use ofthe cam gear.

such as q is employed to connect .80 s andt are respectively the clutchwith spring u and the differential gear, which areshown inclosed sidethereof intermediate its pivots to engage the cam,

and additional means forrotating the drivingshaft acting inconjunction'with the opposite face of the disk.

In witness whereof -we have hereunto set our hands in presence of twowitnesses.
